T-cell receptors orchestrate immune-system responses against infection and cancer. A structure of an entire T-cell receptor complex clarifies its assembly and signalling, and sheds light on its ...

Eukaryotic cells form the foundation of complex life, their defining feature being the presence of membrane-bound organelles. This article details the structure of eukaryotic cells and provides ...

The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665.

Linking RNA structure and function Date: September 9, 2016 Source: Massachusetts Institute of Technology Summary: Several years ago, biologists discovered a new type of genetic material known as ...

Researchers have long been interested in the mechanical properties of the cell nucleus. It is known that these must be well regulated for the cell to function properly and that they can change in ...

Prokaryotes are unicellular organisms that lack membrane-bound structures. This article details the structure of prokaryotic cells and provides examples of prokaryotic organisms.

Research over the years has provided insight into this organ's structure and various functions. As essential components of an effective adaptive immune system, the thymus develops responsive T ...

While the structure of these proteins is quite similar to several shared cytoplasmic, juxtamembrane and transmembrane domains, they also have distinct regions and distributions inside cells.

The Hemifusome: A Cellular Recycling Center The hemifusome is a tiny, membrane-bound organelle that functions as a recycling center inside cells. Its primary role seems to be in organizing and ...

Although known since the 1830s as a round, dark spot in a cell's nucleus, only recently has the nucleolus gotten its full due. Scientists, including research conducted by the lab of Clifford ...

Like bees breathing life into gardens, providing pollen and making flowers blossom, little cellular machines called mitochondria breathe life into our bodies, buzzing with energy as they produce the ...
